In this study, 69 episodic cluster headache (CH) patients (40 in the active phase, 29 in remission period) underwent a complete TCD examination in order to verify the relationship between cerebral blood velocities (CBVs) and the clinical profile of the disease. Fifteen patients were examined during both phases, while 7 were monitored during a spontaneous attack. Sixty-three healthy sex and age-matched controls were also studied. We measured widespread, asymmetric CBV activation during the active phase, bilaterally in the anterior circulation and also in the posterior circulation. A relative reduction of CBV on the anterior cerebral artery pain side, also during remission, suggests a relationship between local vasodilation and the autonomic symptoms ipsilateral to pain during CH attacks.

Abstract

In this study, 69 episodic cluster headache (CH) patients (40 in the active phase, 29 in remission period) underwent a complete TCD examination in order to verify the relationship between cerebral blood velocities (CBVs) and the clinical profile of the disease. Fifteen patients were examined during both phases, while 7 were monitored during a spontaneous attack. Sixty-three healthy sex and age-matched controls were also studied. We measured widespread, asymmetric CBV activation during the active phase, bilaterally in the anterior circulation and also in the posterior circulation. A relative reduction of CBV on the anterior cerebral artery pain side, also during remission, suggests a relationship between local vasodilation and the autonomic symptoms ipsilateral to pain during CH attacks.
